Thats not correct on flights. The flight cost during our summer is much cheaper cos american airlines have seasonal direct flights during this period.
Its during our winter when australians want to go enjoy the national parks in the states and Canada that the prices go crazy high.
My next trip to florida will be in december in part cos I can get cheaper flights then. June/july is way too expensive.
I would of thought its hard to get to the Baltics for Americans. Multiple flights Im guessing. Although I could be wrong.
